Section III. Hazards Identification
Acute Health EffectsCorrosive to skin, eyes, and respiratory system. Liquid or spray mist may produce tissue damage, particularly in mucous
membranes of the eyes, mouth and respiratory tract. Skin contact may produce burns. Eye contact can result in corneal
damage or blindness. Inhalation of the spray mist may produce severe irritation of respiratory tract, characterized by
coughing, choking, or shortness of breath. Corrosive materials may cause serious injury if ingested.
Harmful if ingested or inhaled. Minimize exposure to this material. Severe overexposure can result in injury or death.
Follow safe industrial hygiene practices and always wear proper protective equipment when handling this compound.
Chronic Health EffectsCARCINOGENIC EFFECTS : Not available.
MUTAGENIC EFFECTS : Not available.
TERATOGENIC EFFECTS : Not available.
DEVELOPMENTAL TOXICITY: Not available.
Repeated exposure of the eyes to a low level of dust can produce eye irritation. Repeated skin exposure can produce local
skin destruction, or dermatitis. Repeated inhalation of dust can produce varying degree of respiratory irritation or lung
damage.

Section IV.First Aid Measures
Eye ContactCheck for and remove any contact lenses. In case of contact, immediately flush eyes with plenty of water for at least 15
minutes. Get medical attention.
Skin ContactIn case of contact, immediately flush skin with plenty of water. Remove contaminated clothing and shoes. Wash clothing
before reuse. Thoroughly clean shoes before reuse. Get medical attention.
InhalationIf the victim is not breathing, perform mouth-to-mouth resuscitation. Loosen tight clothing such as a collar, tie, belt or
waistband. If breathing is difficult, oxygen can be administered. Seek medical attention if respiration problems do not
improve.
DO NOT INDUCE VOMITING. Loosen tight clothing such as a collar, tie, belt or waistband. If the victim is not breathing,
Ingestion
perform mouth-to-mouth resuscitation. Examine the lips and mouth to ascertain whether the tissues are damaged, a possible
indication that the toxic material was ingested; the absence of such signs, however, is not conclusive.
